Okay I posted a while ago about our furnace going out. It worked one night and then the next day it was blowing cold air. We turned it off and on again and you can hear it start, but does not complete the ignition cycle. Well, now that our weather is getting a little chilly at night and we have a week planned to camp in October. DH pulled out the furnace to check it yesterday (he is an electrician by trade) and had the troubleshooting schematic and worked his way through the first few things. It is not the limit switch or sail switch. It is a Suburban Furnace SF35FQ. There is no place local to take it to to help troubleshoot. The next step is the igniter but it is so hard to get to he is not sure if we should just purchase a new one or take it the rest of the way apart to keep troubleshooting. We have a Coleman-Mach Thermostat. Any suggestions from the awesome people here would be much appreciated.
Thanks
